[0002] In the production process of woven fabrics, printing is a commonly used decorative process for applying patterns and colors to fabrics. Inkjet printing technology is used to print patterns directly on the fabric. Digital printing is flexible and suitable for mass production. It can achieve complex and colorful patterns.

[0003] When double-sided printing is performed on woven fabrics, it is mainly completed by flipping the single-sided printing and then performing the second printing. During this process, it is inevitable to load and unload the woven fabric after the single printing and transport it for the second time. The operation steps are relatively cumbersome, which reduces work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3The utility model provides a technical solution: it includes a printing box 1, wherein two processing grooves 2 are provided in the printing box 1 and are distributed up and down, a printing chamber 21 and a drying chamber 22 are arranged in the processing groove 2, an inkjet print head 3 is installed in the printing chamber 21, a heating plate 4 is fixed in the drying chamber 22, a front end frame 5 is fixed at the front end of the printing box 1, a pair of driving rollers 51 are rotatably connected in the front end frame 5 and at a position corresponding to the processing groove 2, a guide roller 6 is installed at the rear side of the printing box 1 and at a position corresponding to the processing groove 2, a pair of conveying rollers 23 are installed in the processing groove 2 and at both ends of the processing groove 2, a glass cover 61 is fixed on the back of the printing box 1 and at the outer periphery of the guide roller 6, and a synchronous motor 52 is fixed on the outer side of the front end frame 5 and at a position corresponding to the driving roller 51.

[0018] A pair of positioning sensors 7 are installed in the processing groove 2 and in front of the inkjet print head 3. A sliding block 71 is slidably connected to the upper side wall of the processing groove 2 and corresponds to the positioning sensor 7. The positioning sensor 7 is fixed at the bottom of the sliding block 71. A bidirectional screw 72 is rotatably connected to the upper end of the processing groove 2. The bidirectional screw 72 passes through the sliding block 71 and is threadedly connected to the sliding block 71. A servo motor 73 is fixed in the printing box 1 and at the end of the bidirectional screw 72. The output end of the servo motor 73 is fixed to the end of the bidirectional screw 72.

[0019] A sliding groove 31 is provided at the upper end of the processing groove 2 and at a position corresponding to the inkjet print head 3. A track plate 32 is slidably connected in the sliding groove 31. The inkjet print head 3 is fixed on the track plate 32. An ink cartridge 33 is fixed at the upper end of the sliding groove 31. A connecting hose 34 is fixed between the ink cartridge 33 and the inkjet print head 3.

[0020] Working principle: First, connect the whole device to an external power source, then pass the woven fabric through the upper processing tank 2, and then pass through the lower processing tank 2. During this process, the output end of the synchronous motor 52 is used to drive the driving roller 51 to rotate, so that the woven fabric can be continuously transported. At this time, when passing through the printing cavity 21 in the upper processing tank 2, the inkjet print head 3 can be used for front printing. After printing, the heating plate 4 is used for regional heating to quickly solidify the ink. Then, the guide roller 6 is used to transport the woven fabric, so that the woven fabric is automatically turned over and enters the lower processing tank 2, and the back printing is carried out. Finally, the woven fabric is transported from the bottom. The processing groove 2 opens and flows out, achieving the effect of completing double-sided printing at one time, thereby improving the processing speed. At the same time, before printing, the positioning sensor 7 is used to align and position the two sides of the woven fabric to ensure that the woven fabric is in the middle position of the conveying roller 23. If there is an offset, there must be a positioning sensor 7 that cannot detect the woven fabric. It is only necessary to ensure that the center of the positioning sensor 7 is symmetrical. When printing woven fabrics of different widths, the output end of the servo motor 73 is used to drive the bidirectional screw 72 to rotate, and the sliding block 71 and the positioning sensor 7 can be synchronously slid in the opposite direction to ensure that the distance between the positioning sensors 7 is the same as the width of the woven fabric.
